Also, if \(\operatorname{id}\)  is the identity function of \([\ell ]\) , \(P_{\operatorname{id}}\)  is the identity matrix of size \(\ell \) , so \(M_{/\operatorname{id}}=M\) . This shows that linear minions form a subclass of the so-called abstract minions (or simply minions) introduced in [1]} (see also [2]}).
